While Thursday set a summer record, the overall record for PGE electricity use was 4,073 megawatts, which was set on Dec. 21, 1998 when it was 16 degrees.

For comparison, one megawatt can power an estimated 700 Northwest homes, and 1,200 megawatts can power a city the size of Seattle, according to the Bonneville Power Administration.

The BPA also reported summer record electricity use during the heat wave. They said for the first time ever, more than 8,000 megawatts were consumed, which occurred on Tuesday, Wednesday and Thursday. The peak use of 8,226 megawatts came on Wednesday.

Electricity use will likely remain high as temperatures are expected to stay in the 90s through next week.
